A new Opera Developer update released today brings an interesting new feature: a built-in RSS reader.

To try it out, get the latest Opera Developer and click on "News" on the left sidebar. The new Opera RSS reader allows adding your own custom sources, but it also comes with a news catalog:

To add a new custom source, click "Add sources", then paste the RSS feed in the "Search catalog" box.

Note that the Opera RSS reader doesn't automatically detect the RSS feed if you enter a website URL, or at least that was the case in my test. Instead, you must enter the RSS feed URL (as an example, here's a link to the WebUpd8 feed).
